Title: Peptide and protein fusions to thioredoxin and thioredoxin-like molecules
Inventor: MCCOY JOHN
IPC: C07K14/51
Filed: 1992-02-06
Granted: 2001-10-30
Abstract: This invention provides a fusion molecule comprising a DNA sequence encoding a thioredoxin-like protein fused to the DNA sequence encoding a selected heterologous peptide or protein. The peptide or protein may be fused to the amino terminus of the thioredoxin-like molecule, the carboxyl terminus of the thioredoxin-like molecule, or within the thioredoxin-like molecule, for example at the active-site loop of said molecule. Expression of this fusion molecule under the control of a regulatory sequence capable of directing its expression in a desired host cell, produces high levels of stable and soluble fusion protein. The fusion pro-tein, located in the bacterial cytoplasm, may be selectively released from the cell by osmotic shock or freeze/thaw procedures. It may be optionally cleaved to liberate the soluble, correctly folded heterologous protein from the thioredoxin-like portion.

Abstract: Improved circuits for measuring the conductivity of a solution confined between two electrodes in a cell compensate for series capacitance and parallel capacitance between the electrodes. A bipolar square-wave signal is applied to the cell. In one embodiment, the current through the cell is measured by an op-amp in current-to-voltage converter configuration. A feedback resistance employed with the op-amp in a feedback loop is controlled to a low value to ensure that the parallel capacitance is fully charged during an initial portion of each half-cycle of the drive signal. The feedback resistance is then selected so that the gain of the feedback loop is responsive to the range of the resistivity of the solution, and the measurement is made. The period of the bipolar signal is selected responsive to the selected loop gain, to ensure that a filter capacitor across the op-amp is fully charged, and to limit distortion caused by the series capacitance. More particularly, the rate of charge of the series capacitance is proportional to the solution resistance; by varying the period of the drive signal in accordance with the solution resistance, the distortion introduced by the series capacitance remains negligible.        In a further embodiment, charge proportional to the current through the cell is integrated across the op-amp, and the rate of charge is measured by measuring the time required to integrate the current to a predetermined level, and used to determine the resistivity of the solution. In this embodiment, the parallel capacitance is fully charged before each integration period begins.      The voltage developed across the series capacitance is constant and can be compensated mathematically.

Abstract: The apparent accuracy of a clock circuit used to recover timing and transmitted information signals in a data receiver is improved. A timing relationship inherent in a received signal is detected prior to the acquisition of a timing component embedded in a desired information portion of the received signal. The timing relationship has an accuracy that is greater than the accuracy of the clock circuit. The clock circuit is controlled in response to the timing relationship to operate with an improved range of accuracy. Thereafter, the embedded timing component is acquired and used to control the clock circuit. In an illustrated embodiment, the timing relationship is derived from a symbol rate of the received signal. In an alternate embodiment, the timing relationship is obtained from a separate transmitted reference signal, such as a transmitted television signal.

Title: Needleless hypodermic injection methods and device
Inventor: PETERSON STEVEN FISHER
IPC: A61M5/20
Filed: 1993-07-23
Granted: 2006-07-11
Abstract: A needleless injection device (20) includes an initiator valve (144) controlling flow of compressed gas into a reservoir (168). A poppet valve (170) connecting to the reservoir has a gas pressure regulation end to regulate flow from the initiator valve into the reservoir. A clamp piston (210) is driven forward by gas pressure from the reservoir and causes jaws (236) to clamp onto a plunger (362) extending into an ampule (360). The poppet valve opens when reservoir pressure reaches the cracking pressure of the poppet valve. Gas from the reservoir rushes through the poppet valve into a drive chamber and forces a drive piston (212), containing the clamp piston and jaws, forward causing the plunger to slide into the ampule. A jet of injectant is ejected out of the nozzle of the ampule and penetrates through the patient's skin. An improved method of needleless injection uses a specific pressure profile, ampule nozzle diameter, patient, injection site, and injectant parameters.

Abstract: La présente invention est une extrémité d'échappement pour des appareils installés à l'intérieur d'un bâtiment nécessitant l'emploi d'un tuyau d'échappement pour évacuer l'air vicié ou d'autres sortes de gaz ou de fumées vers l'extérieur du bâtiment. L'extrémité d'échappement que l'on propose, possède une double fermeture qui empêche l'air extérieur d'entrer à l'intérieur du bâtiment et emprisonne une certaine quantité d'air dans un cylindre rotatif situé entre les deux fermetures, agissant ainsi comme isolant thermique entre l'entrée et la sortie de l'extrémité d'échappement lorsqu'elle est en position fermée. Le cylindre possède une plaque agissant à la manière d'un clapet et d'un contrepoids et deux ouvertures rectangulaires dont l'une d'elle située sous le clapet. Le clapet est actionné par le flux d'échappement qui est dévié vers le haut par la conduite d'entrée et poussé faisant ainsi pivoter le cylindre. Le clapet étant poussé vers le haut, le flux d'échappement passe par l'ouverture situé sous le clapet, entre à l'intérieur du cylindre et sort par la seconde ouverture du cylindre ouverte elle aussi lors de la rotation du cylindre. Le flux d'échappement poursuit ensuite son chemin par la conduite de sortie dirigée vers le bas, protégant ainsi le système des intempéries (pluie ou neige ) tout en laissant le flux s'échapper vers l'extérieur du bâtiment.

Abstract: A rotary speed measurement device comprises an oscillator including a resonant circuit with a coil which conducts a resonant current to develop a magnetic field therearound. A wheel is connected to rotate together with a rotating member and is provided along circumference with alternately arranged first and second marks which causes different magnetic effect on the magnetic filed. The coil is disposed adjacent the wheel so as to sense the magnetic effect and provide a corresponding voltage Vs. An analyzer is provided to give a parameter Vsub based upon voltage Vs and to compare the parameter with a predetermined threshold V TH to give a pulse when the parameter exceeds the threshold as indicative of that the wheel rotates by an increment corresponding to an angular distance between the first mark and the adjacent second mark. The pulse is counted by a counter within a unit time to obtain a rotary speed of the wheel. The device is characterized to include a reference circuit connected in circuit with the resonant circuit to provide a reference voltage Vr which is in phase with voltage Vs and varies at a different rate from voltage Vs in response to the inductance change in the coil, and to include a differential low-pass filter which is connected to receive voltage Vs and reference voltage Vr for providing a difference therebetween as the parameter Vsub to be compared at the analyzer with the threshold V TH. Thus, voltage difference between Vs and Vr can represent the parameter of which amplitude is kept within a limited range irrespective of the distance between the coil and the wheel, whereby realizing successful rotary speed measurement without necessitating to care the relative position of the rotor to the wheel, and extending the measurable distance between the coil and the wheel.
